My Thanks to all who responded re the tailings question: but I have obviou=
sly been too coy and not clear enough... It's gamma, not radon, that I am=
 interested in...and I am not enquiring about the effectiveness of cover..=

I have a future hypothetical tailings deposit which will NOT be emitting=
 radon but which is a large area source of strong gammas, at 1 MeV and at=
 2.6 MeV (guess what it is??), and I suspect the gamma doserate standing=
 on the surface of the pile will be about 200 microsieverts per hour.=20

Does anybody have any idea how I might estimate gamma skyshine at a distan=
ce of (say) 200 metres from the boundary of such a source, of area (say)=
 100 m x 100 m ???=20
